To date, Quorum has raised a total of $24.35 million in funding. Earlier this year, the company demonstrated a dual radio IC that combines a W-CDMA 3G transceiver with Wi-Fi 802.11 b/g capabilities for companies readying converged handsets.

The device, not yet sampling, will be the next version of the company's Sereno series of multi-mode radio transceivers for what it describes as ubiquitous wireless connectivity. The chip is called the QS2000 (see Feb. 14 story).

"This additional funding, raised in the Series B, will be used to strengthen ongoing sales and marketing efforts and drive the convergence market from a semiconductor technology aspect as well as to take the QS2000 into full production," according to the company. "In addition to supporting the QS2000, these funds will be used in the development of new products in the handset convergence space."
